Football players often bark at each other, but Raiders linebacker Ray-Ray Armstrong could be in trouble for doing the same to a dog. Of course, this was no ordinary dog, but a K-9 member of the police that was at Heinz Field for Sunday’s Oakland-Pittsburgh game, and according to Pennsylvania law, taunting such an animal can be charged as a third-degree felony.

The incident happened in the stadium tunnel as players were entering the field before the game. A fired-up Armstrong allegedly “lifted his shirt, pounded on his chest and began barking” at the dog, as reported by Marie Cipriani of Pittsburgh’s WTAE.

“We were immediately notified about the incident, and we immediately initiated a criminal investigation into the matter. Sheriff’s Office supervisors interviewed witnesses and reviewed video surveillance recordings at Heinz Field. We notified the District Attorney’s Office on Sunday. The Sheriff’s Office is currently reviewing all of the information and reports to make a final determination relating to charges,” Allegheny County Sheriff’s Office Chief Deputy Kevin Kraus said (via CBS Pittsburgh).

According to Kraus, Armstrong “came out of the locker room, he started jumping up and down, intimidating the dog, calling for the dog. The dog immediately responded and tried to make its way over to the player, the K-9 deputy prevented the dog from doing so.”

Armstrong, in his third year out of Miami, has spent time with the Rams, in addition to the Raiders. Oakland lost, 38-35, to Pittsburgh, which has on its roster Michael Vick, who went to jail for his role in a dog-fighting ring.
